Description

The idea is to take the strengths of the HP48 calculator, and try to get the same capabilities but with a touch screen Android device instead. It is a little limited at the moment. Implemented features: * arbitrary precision float (gmp/mpfr/mpc) * good support for units * RPN calculator * basic scalar operations (sin/exp/etc) * programmability (if you like FORTH or RPL)

Future features: * vector/matrix math * graphing * base conversions

This is (hopefully) under heavy development so if you use it, let me know what you think. Also, let me know if you want access to my source repository.

Great work. Would be happy to donate to assist with finishing touches.

Finally somebody understands what a calculator is this program shows easy to use buttons, it doesn't try to draw an old calculator in you screen, if I need an old calculator i will take it out of my desk drawer. this calculator has a very good units interface i will let you multiply 3 different units (m) (in) (ft) and obtain m3. Like an hp 48 49 or 50. I was wondering why nobody takes the hp 48 or 49 rom and makes a proper emulator for andorid. Stop trying to invent new software just apply what works on the new platform. so far this is the best unit conversion and calculator combination you will find. I you need an excellent plain calculator use RealCalc. I you need to use units use this one. I also like the behavior of the sack on this one better than realcalc.

Tom Good work I like your design so far

Thanks This works well for a nice simple rpn with a few functions. Maybe the undo could go on the front page? Has inverse and swap so I'm happy. Thanks

Great RPN calculator Always wanted a basic RPN calculator with a stack that's viewable/accessible. This one satisfies the viewable but I wish there was a straight forward was to get to a number deeper in the stack. Otherwise the 1/x right there is nice. I use it for basic math.

For example, if a user were to write a new program inside of 'Droid48', the user can then use 'Droid48 Reader' to extract this program as a stand-alone file onto their SD card. From here, the user can do whatever they normally would do with this file such as simply store the program for archival purposes, download this file into a real HP 48 calculator, share it with a friend to load into their own Droid48, or post it on the Internet at sites like http://www.hpcalc.org (note: these are beyond the scope of 'Droid48 Reader').

As another example, the user can read a large stand-alone file that is an HP 48 directory file, navigate to an algebraic equation, then share this algebraic equation via email (requires a separate Android email program that supports sharing).

A stand-alone HP 48 file is a file for the Hewlett-Packard 48-series of calculators (ex: HP 48S, 48SX, 48G, 48G+, and 48GX). More can be read on these calculators on Wikipedia.

'Droid48' is an Android program which emulates an HP 48GX calculator on Android. It is independently developed (not developed by Drehersoft) and is a separate program from 'Droid48 Reader'. 'Droid48' is available on Google Play.

When using 'Droid48 Reader' with 'Droid48', it is important to first use the Save memory/state menu in 'Droid48'. This saves its data to the SD card. After doing this, return to 'Droid48 Reader' and select Refresh Droid48 from the menu.

HP-45 scientific calculator is a true hardware emulation of the classic HP-45 calculator will behave just like the original.

The following Android functions are supported:

• Calculation results can be copies to the clipboard.• Can be installed on the SD-Card.• Participates in Androids build in backup and restore.• Honeycomb Tablet compatible.• Extra Printer for Honeycomb Tablets (visit our web-page for screen shot).

Developed by HP, the HP 15C Android Calculator App is an exact replica of the original layout, functions, algorithms and calculation sequences you trusted to help you through college and your career. When you find yourself without your HP 15C scientific calculator, relax – just open it on your favorite Android device.

FX-603P Simulator is a very precise simulation of the classic FX-603P programmable calculator and all it's accessories. This simulation is not a toy but but a full features simulations of almost functionality of the original calculator and it can be used as a full featured and fully programmable scientific calculator.

Used as a calculator the FX-603P simulator will exceed most other calculator available. The FX-603P simulator supports all arithmetic, trigonometric, logarithmic, hyperbolic, statistical functions and all alphanumeric display options of the original calculator.

And last not least the FX-603P simulator is fully programmable. You can write up to 20 programs, using 110 registers.

With the build in FA-6 cassette interface simulation you can save and load programs and data to your thump drive for later use. Or printout results with the FP-10 thermal printer simulation and then copy / paste them to other applications.

Do visit our FX-603P website or blog where you can download the original Manual of the Calculator. Remember that the Market-Comments have no answer function and I can't help you if you post there.

SUPPORTED ANDROID FUNCTIONS:

• Calculation results can be copies to the clipboard.• Can be installed on the SD-Card.• Participates in Androids build in backup and restore.• Tablet compatible.• Extra Printer for Tablets.

A unique calculator with no equals button - it has two text entry fields, one where you enter an expression, the other provides a running total. You can switch between them at any time, using the result of a previous calculation in a new one.

A stroboscopic tuner. You tell it which note you are aiming for, and then it will show you a red/green bar indicating how close you are coming to hitting it. Perfectly horizontal means you are in tune, sloping down is flat, and sloping up is sharp.

An FFT spectrum analyzer. You can see how the complete spectrum evolves over time.

TunerTime is not the simplest tuner to use, but it is probably the most precise, and it has features particularly useful for piano tuners.
